e. This indicates that the EPF has been turned off due to an overc urrent
condition at the voice ter minal. Check for defective wiring or a damaged
jack, and make sure the voice te rminal is a Hybrid set. Once the problem
has been resolved, the alarm is retired after a predetermined p eriod of
time.
f. This indicates that the voice term inal has probably bee n disconnected o r
that there is a problem in the wiring to t he terminal. Make sure that the
voice terminal is connec ted or check for d efective wiring to the voic e
terminal.
g. Note that Error Types 769 and 1281 by themselves create Warning alarms
only, but if both are present, a Minor alarm is logged.
h. This indicates that there is something wrong with the d ata link to the voice
terminal. An in-line maintenance error has g enerated an off-board
warning. Ignore it if there are no co mplaints. Otherwise, make sure the
voice terminal is connec ted, check for d efective wiring, chec k for a
defective voice term inal, and move voice terminal c loser to the switch (in
terms of feet of wire from the jack to the switch). If t he problem still exists,
replace the circuit pack.
i. This indicates that the station went off-hook while in the d isconnect state.
Use the status station command to determine the state of the station. The
off-hook should have moved the station to in -service. No system
technician action is nec essary.
j. This is the code that is generated when the link between the circuit p ack
and the voice terminal is suc cessfully reset. No system technicia n action
is necessary.
